Safety Information
Always read and understand all safety warnings and instructions before operating the pressure washer. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.
- Electrical Safety: Ensure the power outlet is properly grounded. Do not operate the pressure washer in wet conditions or near standing water. Always use a Ground Fault Circuit Interrupter (GFCI) protected outlet.
- Water Connection: Connect the pressure washer only to a cold water supply. Do not use hot water. Ensure all connections are secure to prevent leaks.
- Personal Protective Equipment: Always wear appropriate eye protection (safety goggles), hearing protection, and protective clothing (gloves, long pants, closed-toe shoes) when operating the unit.
- Nozzle Safety: Never point the spray gun at people, pets, or electrical devices. The high-pressure spray can cause serious injury.
- Child Safety Lock: The handle is designed with a child safety lock to prevent accidental activation. Always engage the safety lock when the unit is not in use or unattended.
- Total Stop System (TSS): This unit is equipped with a Total Stop System, which automatically shuts off the pump when the trigger is not activated. This saves energy and prolongs the life of the pump and motor.
